Abstract
The invention discloses casing forming pressurize process outside a kind of car antenna, four sections of settings of pressurize point：First paragraph selects benchmark packing pressure, and the dwell time is 0.4 0.7 seconds；For second segment by benchmark packing pressure rise 50% 70%, the dwell time is 0.2 0.4 seconds；3rd section is selected benchmark packing pressure, and the dwell time is 13 seconds；The 50% of 4th section of selection benchmark packing pressure, dwell time are 13 seconds.By recognizing again to condition of molding, existing setting means is overturned, improves the outward appearance demand of product, particularly solves burr and the contradiction shunk.It is the antenna casing class product (it is required that high smooth surface) on automobile to improve object, as products such as car antenna shells, burr, contracting hole, the comprehensive solution of the problems such as starved, the use of this technique, allows fraction defective to have dropped more than 80%, in the state of can not ensure that burr, the bad phenomenon of do not contract hole and starved.
Description
Technical field
The present invention relates to plastics molding process technical field, more particularly to a kind of outer casing forming pressurize technique side of car antenna
Method.
Background technology
In forming process, suitable condition of molding is selected, outward appearance to product and its important.Car antenna shell product
Very harsh to appearance requirement, existing shaping pressurize mode is generally such as Fig. 1 and Fig. 2 bodyguard sample, the ripe shaping of current use condition
Dwell condition can not meet overlap, the bad phenomenon such as contracting hole and misrun simultaneously.
The content of the invention
The present invention is to solve the problems, such as shaped article bad order, there is provided a kind of outer casing forming pressurize technique side of car antenna
Method, have to burr, contracting hole and misrun etc. and solve effect well.
In order to solve the above technical problems, the technical scheme is that：The outer casing forming pressurize process of car antenna, bag
Include following steps：Matched moulds, injection, pressurize, cooling, die sinking, ejection, taking-up product, four sections of settings of pressurize point：First paragraph selects base
Certainly pressure, dwell time are the 0.4-0.7 seconds；Benchmark packing pressure is raised 50%-70%, dwell time 0.2- by second segment
0.4 second；3rd section is selected benchmark packing pressure, and the dwell time is the 1-3 seconds；4th section from the 50% of benchmark packing pressure, during pressurize
Between be the 1-3 seconds.
Preferably, benchmark packing pressure is raised 60% by second segment.
Preferably, the first paragraph dwell time is 0.5 second.
Preferably, the second segment dwell time is 0.3 second.
Preferably, the 3rd section of dwell time is 2 seconds.
Preferably, the 4th section of dwell time is 2 seconds.
The beneficial effects of the invention are as follows：By recognizing again to condition of molding, existing setting means is overturned, improves production
The outward appearance demand of product, particularly solve burr and the contradiction shunk.It is that the antenna casing class product on automobile (is wanted to improve object
Seek high smooth surface), as products such as car antenna shells, burr, contracting hole, comprehensive solution the problems such as starved, this technique
Use, allow fraction defective to have dropped more than 80%, it is ensured that do not go out in the state of burr, the bad phenomenon of do not contract hole and starved.
Brief description of the drawings
Fig. 1 is that pressurize mode one is molded in background technology；
Fig. 2 is that pressurize mode two is molded in background technology；
Fig. 3 is the shaping pressurize mode of the present invention.
Embodiment
As shown in figure 3, the outer casing forming pressurize process of car antenna, comprises the following steps：It is matched moulds, injection, pressurize, cold
But, mold, eject, taking out product, four sections of settings of pressurize point：First paragraph selects benchmark packing pressure, dwell time 0.4-0.7
Second, preferably 0.5 second；Second segment by benchmark packing pressure raise 50%-70%, preferably 60%, the dwell time is the 0.2-0.4 seconds, excellent
Select 0.3 second；3rd section is selected benchmark packing pressure, and the dwell time is 1-3 seconds, preferably 2 seconds；4th section from benchmark packing pressure
50%, the dwell time is 1-3 seconds, preferably 2 seconds.The requirement of the numerical basis product that benchmark packing pressure is specifically set adjusts, into
Type machine should possess the function (ability that 30% pressure above can be lifted in 0.1 second) of transient response speed.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope of present disclosure, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
